8 Claims. (CI. 136-134) This invention relates to improvements in storose better-les.

An object of the invention is to provide an improved storage battery wherein the plates of the battery are structurally connected together at their bottom so as to reduce buckling of the plates and danger due to vibration.

Another object of the invention is to provide a storage battery wherein all positive plates are oonnected together at their bottoms electrically and in a. similar manner, all negative plates will be connected together at their bottoms electriooily. With such an electrical connection it 'is possible to charge and discharge the plates if they become broken either through the center or become detached from the terminal.

Another object of the invention is to provide a storage battery wherein the plates have downwardly extending extensions or legs which are integral with their respective plates and which are sufliciently long that when welded together they will rest fi'miy on the flat bottom of the batte'y eontainer. such an arrangement supporte the weight of the assembled plates directly on the bottom of the container and indces the normally cold and dormant acid which lies near the bottom of the container to rise and circulate up through the cell whenever the plates become hot.

Still another object of the invention is to provide a battery wherein the container has upstanding ribs or webs on the bottom thereof and wherein the sn'uotural and electrical connections between the bottoms of the positive and negative plates, respeotively, are disposed on opposite sides of the upstanding ribs or webs with the bottom edges of the plates supported by the legs or extensions above the ribs. This arrangement eliminates the wearing of the plates into or by the rib. Oxide tending to settle has little, if any, opportunity to rest on top of the rib and short cil-enit between the connections at the bottoms of the positive and negative plates. An adoquate space is also provided for the free circuiaiion of eleotrolyte. e

With the oregong and other objects in View which will be made manifest in the following detailed description and speciflcally pointed out in the appended claims, reference is had to the aeoompanying drawings for an illustrative embodiment of the invention, wherein:

Figura l is a view in side elevation of one ot the battery plates employed in the battery embodying the present invention;

Hg.2isaperspectiveviewofaeroupofas-l 2 sembled plates of the battery embodying the present invention; and

Fig. 3 is a transverse section through the battery embodying the present invention.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, alternate plates constituting positive plates indicated at ill are illustrated as having upper extensions H at their upper right-hand corners which are attachable to a bus bar !2 that is connected to the positive terminal !3. These plates have downwardly extending extensions or legs M at their lower lefthand comers and similar legs |5 that are spaced inwardly from the lower right-hand comers of these plates. In a similar manner, the intermediate plates constituting negative plates have upwardly extending extensions i 6 near their lefthand corners attachable to a bus bar ll leading to a negative terminal is and these plates have downwardly extending extensions s at their lower right-hand corners and similar legs 20 that are spaced inwardly from their lower leit-hand corners.

When the plates are assembled together, bars or feet z, 22, 23, and 24 are burned or welded onto the legs M, 20, and !5 and !9, respectively. These bars or feet serve to structurally connect the plates at their bottoms and electrically connect the positive plates and the negative plates, respectively near their bottoms. The separators between the plates are indicated at 25.

When the plates have been thus assembled they are placed in a container 26 containing any usua or conventional electrolyte and this container has on its bottom a. plurality oi' upstanding ribs or webs 21, 28, 29, and 30. The top edges of the ribs or webs are spaced slightly from the bottom edges from the bodies of the plates. 'The bars or feet 21, 22, 23, and 24 rest on the bottom of the container 26 with the bars z and 22 disposed on opposite sides of the `web 21. In a similar manner, the bars or feet 23 and u are disposed on opposite sides of the web 30. The webs 28 and 29 are between the bars or feet 22 and 23. With this arrangement the weight of the plates is supported directly on the bottom of the container 26 and by reason of the structural connections between the bottoms of the plates they are flrmly held in position even under vibration. The bars or feet also provide electrical connections between positive and negative plates. respectively. Any oxide tending to set- ,tle in the container has little, it any, opportunity u, and u. consequently, there is little. i: any, opportunity o! short circuiting taking place between bars !I and 22. 23 and 24. or 22 and 23.

I claim as my invention:

A storage battery comprising a case having upstanding webs on the bottom thereoi, positive and negative plates within the case, and legs on the plates supporting the plates on the bottom o! the case, the legs of the positive plates being arranged on the opposite side o! a web from that on which the legs oi the negative plates are arranged.

2. A storage battery comprising a case having upstanding webs on the bottom thereoi, positive and negative plates within the case, and legs on the plates supporting the plates on the bottom oi the case, the legs of the positive plates being arranged on the opposite side of a web from that on which the legs of the negative plates are arranged. the body of the plates being supported by the legs in spaced relation to the tops oi' the webs.

3. A storage battery comprising a case having upstanding webs on the bottom thereof, positive and negative plates within the case, legs on the plates supporting the plates on the bottom of the case, the legs of the positive plates being arranged on the opposite side of a web from that on which the legs of the negative plates are arranged. conducting means connecting the legs of the positive plates together, and conducting means connecting the legs oi the negative plates together.

4. A storage batterycomprising a case, positive and negative plates in the case. legs on the plates supporting the plates on the bottom oi' the case, and means on the bottom of the case disposed between the positive plate legs and the negative plate legs for preventing oxides settling to the bottom of the case from shorting between the positive and negative legs.

5. A storage battery comprising a case, positive and negative plates in the case. legs on the plates supporting the plates on the bottom of the case, and upstanding webs on the bottom of the case arranged between the positive legs and the negative legs.

6. A storage battery eomprising a case, positivo and negative plates in the case. legs on the plates supporting the plates on the bottom oi the case. conducting means integrally connecting the bottoms of the positive legs. conductin means integraly connecting the bottoms oi the negative legs, and meam on the bottom ot the case interposed between the connected positive legs and the connected negative legs i'or preventing aetting oxides from shorting between the l ts.

7. A storage battery comprising a case. positive and negative plates in the case, legs on the plates supporting the plates on the bottom oi the case. conducting means integ'aly connecting the bottoms of the positive legs. conducting means integraiy connecting the bottoms of the negative legs. and upstanding webs integral with the bottom `oi the case interposed between the connected positive legs and the connected negative legs !or preventing settling oxides !rom shorting between the legs.

8. In a storage battery a group of positive plates and a group of negative plates, each group having means adjacent aligned upper corners thereot !or connecting the plates to a battery terminal. the lower. diagonally opposite corners of the plates of each group having downwardy extending legs thereon integrally connected together. the plates oi' each group having other legs on the bottom edges thereof integrally connected together and spaced inwardiy !rom the other lower corners of the plates.
